A. General. Sanitary sewer, storm sewer, water distribution, electrical, gas, telephone and communications, cable and all other utility lines shall be installed in rear lot easements or alleys wherever practical. Where it is impractical to install such utility lines in rear lot easements, they shall be installed within the unpaved portions of the street right-of-way except for sanitary and storm sewer lines which may be installed in the paved portion of the street right-of-way if it is impossible to install them in the unpaved portion. All utility lines will be buried underground according to accepted installation codes.
2. When it is impossible to install sanitary and storm sewer lines in the unpaved portion of the street right-of- way, all such utility lines, including service connections, shall be completely installed and inspected and approved by the planning administrator, following the grading of the street and prior to the application of any pavement base.
3. Where sanitary and storm sewer lines are to be installed in the unpaved portion of the street right-of-way, the installation of service connections may be delayed; provided, that at such time as these service connections are installed, they may be installed without breaking or weakening the existing pavement. Where rock is known to exist beneath the pavement area at such depth as to interfere with the installation of service connections, the complete installation of service connections shall be required prior to the application of any pavement base.
B. Water Supply Improvements. Where the public water supply is reasonably accessible or available to the proposed subdivision, as determined by the city council, a complete water distribution system which shall adequately serve all lots, which shall include appropriately spaced fire hydrants, and which shall be properly connected with the public water supply system, shall be installed. Where a public water supply system is not reasonably accessible to the subdivision, alternate water supply facilities approved by the city council and the South Dakota Board of Water and Natural Resources, SDCL 34-A-2-3 et seq., shall be installed.
C. Sanitary Sewer Improvements. Where the public sanitary sewer system is reasonably accessible or available to the proposed subdivision, as determined by the city council, a complete sanitary sewer system which shall adequately serve all lots and which shall be properly connected to the public sanitary sewer system shall be installed. Where a public sanitary sewer system is not reasonably accessible to the subdivision, alternate community sanitary sewer facilities, which shall be approved by the city council and the South Dakota Board of Water and Natural Resources, SDCL 34-A-2-3 et seq., shall be installed. In the event a community sanitary sewer is determined to be necessary by the city council and the South Dakota Board of Water and Natural Resources, SDCL 34-A-2-3 et seq., the same shall be installed and provision for its continued maintenance shall be established. In any case, sanitary sewer facilities shall be installed as required by standards and specifications as approved by the city council and the South Dakota Board of Water and Natural Resources, SDCL 34-A-2-3 et seq.
D. Storm Drainage. An adequate drainage system, including necessary open ditches, pipes, culverts, intersectional drains, drop inlets and bridges for the proper drainage of all surface winter shall be installed. Cross drains shall be provided to accommodate all natural winter flow and they shall be of sufficient length to permit full width roadways and the required slopes. (Ord. 433 (part), 1995)
